Alternating currents cause Jupiter's aurora

An international team of researchers has succeeded in measuring the current system responsible for Jupiter's aurora. Using data transmitted to Earth by NASA's Juno spacecraft, they showed that the direct currents were much ...

Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...

Artificial muscles powered by glucose

Artificial muscles made from polymers can now be powered by energy from glucose and oxygen, just like biological muscles. This advance may be a step on the way to implantable artificial muscles or autonomous microrobots powered ...

Dowsing for electric fields in liquid crystals

You may not know it, but you probably spend several hours a day looking at nematic liquid crystals; they are used in virtually every smartphone, computer and TV screen. They are liquids composed of elongated molecules, which ...

Electric current

Electric current is the rate of flow of electric charge. The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma.

The SI unit of electric current intensity is the ampere. Electric current is measured using an ammeter.
